WHtR 2026 — The New Military Waist-to-Height Screen
The Department of Defense replaced height-and-weight tables with the waist-to-height ratio on January 1, 2026. This is the plain-English record of what changed, who uses which gate, and whether you pass. Verified 2026-08-19.
Why the change
On December 18, 2025, the U.S. Department of Defense (memo "Additional Guidance on Military Fitness Standards") replaced traditional height-and-weight tables across the joint force with a Waist-to-Height Ratio (WHtR) screen, effective January 1, 2026. A WHtR below 0.55 passes the initial screen; at or above 0.55, a service member receives a secondary body-fat evaluation. DoD Instruction 1308.03 sets the allowable body-fat corridor: no branch may be more restrictive than 18% (men) / 26% (women) or more lenient than 26% (men) / 36% (women). Members are assessed twice per year.

| 2025-12-18 | DoD memo "Additional Guidance on Military Fitness Standards" announces the joint-force switch from height-and-weight tables to the waist-to-height ratio (WHtR) screen. |
| 2026-01-01 | WHtR screen effective across the joint force. WHtR < 0.55 passes the initial screen; at or above 0.55 triggers a secondary body-fat evaluation. DoD Instruction 1308.03 corridor: no branch stricter than 18% (men) / 26% (women), no branch looser than 26% (men) / 36% (women). |
| 2026-01-01 | Marine Corps implements a tighter WHtR gate of < 0.52. |
| 2026-07-07 | Army Directive 2026-13 formally adopts the WHtR < 0.55 screen as the Army Body Composition Program entry gate, superseding the 2023 one-site abdominal tape test as the primary screen. |

| Firefighter | No federal gate | First responder | NFPA 1580 (2025) — Standard for Emergency Responder Occupational Health and Wellness · CPAT |
| Police / LE | No federal gate | First responder | Varies by state & agency (e.g., POPAT, state POST agility tests) |

Verdict by branch (2026)
| Branch | WHtR gate | Your ratio | Result |
|---|---|---|---|
| Army | < 0.55 | 0.486 | PASS |
| Navy | < 0.55 | 0.486 | PASS |
| Air Force | < 0.55 | 0.486 | PASS |
| Marine Corps | < 0.52 | 0.486 | PASS |
| Coast Guard | < 0.55 | 0.486 | PASS |
| Space Force | < 0.55 | 0.486 | PASS |
| Firefighter | — | 0.486 | NO WHtR GATE |
| Police / LE | — | 0.486 | NO WHtR GATE |
A PASS clears the initial WHtR screen. At or above the gate, the service runs a secondary body-fat evaluation (DoD Instruction 1308.03 corridor: 18–26% men / 26–36% women depending on branch and age). Estimates are educational — confirm with your command.
What the old standards were (and why they are gone)
Before 2026, each service used its own height-and-weight table as the entry screen — the Army added a one-site abdominal tape test in 2023, the Navy used a circumference formula, and the Air Force used an abdominal-only measurement. Research consistently showed waist-to-height ratio predicts cardiometabolic risk more accurately than BMI or weight alone, and a single joint-force screen simplifies administration across the services. The old height-and-weight tables were retired as the entry screen effective January 1, 2026; body-fat tables remain only as the secondary evaluation.
